Title: Traveling object communication method
Inventor: NAKAGAWA MASAO
IPC: H04W84/08
Filed: 1990-03-02
Abstract: PURPOSE:To improve the reliability of a control channel and the safety by utilizing plural guard bands between speech channels so as to send a control signal subject to spread spectrum by the frequency hopping system. CONSTITUTION:A control signal A such as outgoing and incoming signals at a sender side I is subject to spread spectrum modulation through a signal spread circuit 11, while a speech signal B such as a data and a voice signal is modulated through an PM or FM modulation circuit 12. The control signal A and the speech signal B are selected by a switch 14 at a control circuit 13 and sent through an RF circuit 15. A receiver side 11 uses a control circuit 17 to select a reception input signal through an RF circuit 16 by a switch 18, separated into the control signal A and the speech signal B and demodulated to obtain required information. Thus, the transmission quality and secrecy of the control channel are improved.

Title: Clutch control method
IPC: F16D48/02
Filed: 1992-03-11
Abstract: PURPOSE:To reduce oscillation and improve safety by selecting a target clutch pressure corresponding to a creep rate based on an operation mode by means of an electronic control means, and thereby controlling a transmission torque of the clutch. CONSTITUTION:A clutch pressure of an oil passage 64 is adjusted by a clutch pressure control valve 52 which is controlled through an output pressure of a three-directional solenoid valve 58, and fed back as a clutch pressure 202 inside an electronic control part 98 by means of a hydraulic pressure sensor 68. In respect to determination of a target clutch pressure by means of the electronic control part 98, the target clutch pressure is set through computation of other target clutch pressure in case that it is not in a hold mode. In case that it is in the hold mode and fast idling, a map for lower creep is selected so as to obtain a lower value, and the target clutch pressure corresponding to the present engine speed. In case that it is not in first idling, the clutch pressure is determined based on a map for a normal creep. Controlling is thus performed with a normal creep rate, so that oscillations of a vehicle at the time of braking are reduced, and safety is improved since a normal operation is necessitated.

Title: Shift seal device of oil-free fluid machine
Inventor: MURAMATSU MASATOSHI
IPC: F04C27/00
Filed: 1986-03-12
Abstract: PURPOSE:To make it possible to improve sealing effect by forming a screw seal portion with spiral grooves over entire inner circumference diameter side length of a sleeve body including its overhang portion which is not inserted into its casing, thereby extending the spiral groove length. CONSTITUTION:As oil which has lubricated a bearing 4 is thrown outside a shown with an arrow 20 due to centrifugal force of a shaft 4 and falls to an oil discharge hole 7 like the oil 23 shown in black in a space 26 on the outer side of a screw seal 15, leakage out of a gap of the seal 15 is restricted. Also, as a long range of screw seal portion including an overhang portion which is not inserted into a casing 1 is formed on the inner circumference of a sleeve body of the screw seal 15, the sealing effect is improved. Accordingly, a spiral groove length can be increased without increasing a span between bearings in the axial direction of an oil-free screw compressor and without narrowing an oil discharge passage. As a result, good sealing effect can be obtained.

Title: Slot-strip line balanced modulator
Inventor: OGAWA HIROTSUGU
IPC: H03C1/58
Filed: 1981-04-10
Abstract: PURPOSE:To realize the switching of a large power carrier wave as well as a miniature constitution of a circuit, by dividing a conductor part enclosed by two slot lines by providing the slot line. CONSTITUTION:The carrier signal is applied to a port 1, and at the same time the pulse is applied to ports 15 and 15A. The pulse signal is applied to diodes 9 and 9A via metallic wires 7 and 7A. A slot line 18 is connected to a slot open part 20, and the length of the line 18 is selected at about 1/4 wavelength. As a result, the impedance is set at zero when the line 18 is viewed at an intersection (diode side) between slot lines 19 and 19A to cause a short circuit with a high frequency. Accordingly no carrier signal is transmitted to the line 18, and the carrier signal is transmitted to the lines 19 and 19A. The carrier signal is extracted in the form of a signal received 0-pi modulation through a microstrip line 10 via the lines 19 and 19A since the route is switched by the diodes 9 and 9A. As a result, the pulse signal of a large amplitude can be supplied to the diode.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To obtain a new dye having specific substituent(s) in the molecule, excellent in dyeing ability and decolorability, and exhibiting high sensitivity as a spectroscopic sensitized dye for photographic use in particular. SOLUTION: This new method dye has at least one substituting of formula I [R1 to R3 are each H, a (substituted) alkyl or aryl, or such a group of atoms as to be needed for forming an N-contg. 5 to 18-membered ring through mutually linking R1 and R2 or R2 and R3 ] (e.g. a methine dye of formula II). The dye of formula II can be easily synthesized by the following well/known process: dichloromethane is added to N-dimethylacetamide followed by addition of chlorosuldfnyl isocyanate to form an intermediate of formula III which is then converted to a second intermediate of formula IV leading to the objective dye. Thereby, this dye is hopeful of high sensitivity as a spectroscopic sensitized dye for silver halide-based photographic photosensitivity materials with low residual color due to dye contamination.

Since the film is taken out from the supply magazine and the film is carried to the housing magazine by the respective pairs of rollers, it is unnecessary to provide a guiding plate and an intermediate roller in a carrying path like the conventional device. Then, the number of parts is reduced and the cost is reduced.
